Wifi = does not mean anything?

The original Wifi name doesn't really mean anything. It was not until later that it was given the phrase "wireless fidelity" in English .

About the name Wifi, many people do not really understand this name. According to the research, the name Wifi was derived from the merging of wireless connectivity standards in the US, originating in 1985. Thanks to the success of Ethernet wired network, some companies began to realize that verification Setting up a common wireless standard is very important.

After a negotiation period, 6 companies including Intersil, 3Com, Nokia, Aironet (later merged by Cisco), Symbol and Lucent announced to link together to create WECA Wireless Ethernet Compatible Alliance. WECA was born with the purpose of confirming products of network providers must be really compatible with each other.

However, terms like 'WECA compatible' or 'compliant with IEEE 802.11b' are still confusing for the whole community. New technology needs a convenient way to call consumers. Experts recommend a number of names like 'FlankSpeed' or 'DragonFly' . but, things are still in place.

Finally, a name 'lucky' gets consensus from all sides: it's the name Wifi. It is explained that the simple, memorable 'Wi-Fi' call sounds like high-quality technology because it is close to hi-fi. So the name Wi-Fi was born. An explanation of 'Wi-Fi means wireless fidelity' is thought of later. Therefore, in fact, the name Wi-Fi is just a name that is easy to call, not an initial meaning.

Wifi is currently deployed widely used around the world, with coverage of about 50 meters. The new version of Wi-Fi is now known as 802.11g, using a more advanced broad spectrum technique called orthogonal frequency-division multiplexing (OFDM) and can reach speeds of up to 54 Mb / s in the 2.4 Ghz band.
